Join Moshe Weitzman (http://drupal.org/moshe) for a deep dive into the page render system for Drupal 7. We'll learn how to build and theme a standard page callback. Then we'll evaluate various alternatives for modifying the page, to meet some challenging user experience requirements. Learn about the security, performance, and maintainability improvements provided by the new hide(), show() and render() functions.
